Review and payment date changed

I just got my text today they have made decisions about my pip review. I call them because I couldn’t wait the two week. When I got through ti the automated service it said how much next pip amount and date suppose to be every Friday 18th April but now says 17th April. Have they changed my payment date? I got through to someone and been awarded both enhanced for both parts till 2028 April but I forgot to ask them about the payment date ???

Regards
